"History
Patents for air cooled clothing have been around for years, but few products have actually made it to market. Hiroshi Ichigawa, a former Sony engineer spent 6 years to develop Kuchofuku, or "air-conditioned clothing" and launched his company in 2004 to manufacture and sell it.[2][3] He first developed the water cooling system, but changed it to the air cooling system later because it was too uncomfortable to feel wet cloth.[3] Another company that brought air conditioned shirts to market is Octocool, which is an online distributor of air cooled clothes.[4] Attached to the clothing are two lightweight fans that help draw in air and help vaporize sweat. The fans, attached to the back of the clothing near the waist, are about 10 cm wide and run on rechargeable lithium ion batteries that last between 8.5 and 59 hours depending on the speed of the fan."
